MACHINE FOR REDUCING RAILS.

SPECIFICATION forming part of Letters Patent No. 408,933, dated August 13, 1889. Application filed July 9, 1889- Serial No. 316,952. (No model.)

To all whom, it may concern.-

Be it known that we, \VILLIAM SCHOLL and THEODORE G. WOLF, of Scranton, in the county of Lackawanna and State of Pennsylvania, have invented a new and Improved Machine for Reducing Rails, of which the following is a full, clear, and exact description.

The object of the invention is to provide a new and improved machine which is simple and durable in construction, very eifective in operation, and serves for rerolling and reduc-' ing old steel rails from a larger to a smaller cross-section without lapping or welding.

The invention consists of rollers, guards, and side guides held on the said guards, both leading to the rollers.

The invention also consists of certain parts and details and combinations of the same, as will be hereinafter fully described, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of the improvement. Fig. 2 is a sectional side elevation of the same on the line a: a: of Fig. 1. Fig. 3 is an enlarged front view of the guards and side guides. Fig. 4 is a sectional side elevation of the same on the line 3 y of Fig. 3. Fig. 5 is an enlarged plan view of the same with parts broken out. Fig. (3 is an enlarged front View of a modified form of the guards and side guides. Fig. 7 is a cross-section of the ordinary'rall. Fig. 8 is a like view of the reduced rail, and Fig. 9 is an enlarged section of the pass or groove in the rollers.-

The improved machine A is provided with the standards B B, in which are mounted to turn lower rollers 0, middle rollers I), and upper rollers E, forming the several passes or grooves F G H I J K L. The first pass or groove F is formed in such a manner as to receive the old rail in an inverted position, while the next pass G is turned one-quarter. The following pass II is also in a similar position to the pass F. The following passes alternately change position in the manner described, and shown in Fig. 1.

The standards B 13 support in the front and rear the beams N, on each of which are mounted sets of guards O, secured in place on the beams N by bolts or other suitable means. 011 each set of guards O are held the side guides P, either directly formed on the guards O or secured in the same in any suitable manner by bolts, or by a dovetail, as shown in Fig. The guards O, as well as their side guides P, extend inward toward the passes F and II from-the front and the rear, as is plainly shown in Figs. 1 and 2.

The outer ends P of the side guides P are somewhat rounded off, so as to permit the easy entrance of the rail under treatment. The inner ends P are shaped to conform to the shape of the rollers C. (See Fig. 2.) In order to conveniently guide the rail to the guards and guides O and P,aroller Q is preferably mounted in the front ends of the guards 0 directly under"the guides P, as is plainly shown in Figs. 3, 4c, and 5. The rail R to be reduced is first properly heated and then passed in an inverted position between the first set of guards O and guides P, leading to the pass F. The guides P are shaped so as to conform reasonably close to the rail-section, in order to sustain the rail in a vertical position while passing through the pass F between the rollers C and D, whereby a reduction in the height of the rail, mainly in the web of the same, is obtained. Said guides and guards may be used only on the roller side of the machine; but they may also be used on the catcher side, as shown in Fig. 2.

After the rail has left the pass F it is introduced into the pass G, and after leaving the latter is passed through the passes II, I, J, K, and L in the usual manner. In case of rolling a rail from blooms or billets the guides I on the second set of guards O are removed, while all other guides remain. By this device one set of rollers can be used for reducing either large rails or blooms to light rail-sections when preceded by the ordinary roughing-rollers.

It is well known that steel cannot readily be welded to steel, and that steel when lapped upon itself fails to weld and will leave a seam over the plicated section. By the machine above described rails can be rerolled without lapping or welding.

Having thus fully described our invention,

we claim as new and desire to secure by Let of side guides held on the said guards and I0 ters Patent-- conforming closely to the shape of the rail,
